Terminology3.1 Definitions of Term

18、s Specific to This Standard:3.1.1 decommission, vtto remove a nuclear facility safelyfrom service and reduce residual radioactivity to levels thatpermit release of the property or facility for unrestricted useand termination of any applicable license(s).3.1.2 decontamination, nthose activities emplo

19、yed to re-duce the levels of (radioactive) contamination in or on struc-tures, equipment, materials, and personnel.3.1.3 dismantlement, nthe alternative in which the equip-ment, structures, and portions of a facility and site containingradioactive contaminants are removed or decontaminated to alevel

20、 that permits the property to be released for unrestricteduse shortly after cessation of operations.3.1.4 entombment, nconsists of placing the facility intoprotective storage. Initial entombment activities consist ofremoving the balance of plant contaminated components,systems, and structures from t

21、he site and sealing all theremaining contaminated and activated plant components andsystems within the entombment boundary. This structure pro-vides for containment of the entire radioactive inventoryremaining on site during the entombment period. Other initialactivities would consist of processing

22、and removing radioac-tive waste, securing a possession-only license, and implement-ing security and surveillance plans for the delay period.Decommissioning is completed by either radioactive decay tounrestricted use levels or by dismantlement to unrestricted uselevels. If dismantlement were selected

23、 following entombment,additional activities would be initiated after 30 or more yearsand would consist of radiation surveys, removal of the entomb-ment structure and materials within it, processing and removalof any remaining solid and liquid radioactive wastes, andrestoring/releasing the site for u

24、nrestricted use.3.1.5 nuclear facility, na facility whose operations in-volve (or involved) radioactive materials in such form orquantity that a radiological hazard potentially exists to theemployees or the general public. Included are facilities that are(or were) used to produce, process, or store

25、radioactivematerials. Some examples are nuclear reactors (power, test, orresearch), fuel fabrication plants, fuel reprocessing plants,uranium/thorium mills, UF-6 production and enrichmentplants, radiochemical laboratories, and radioactive waste dis-posal sites.3.1.6 safe storage, nconsists of placin

26、g and maintainingthe facility in protective storage. Initial safe storage operationswould consist of general plant decontamination activities,radiation surveys, the processing and removal of radioactivewaste materials, securing a possession-only license, and theimplementation of security, surveillan

27、ce, and maintenanceplans for the delay period. Decommissioning is completed bydismantling following the protective storage period. The addi-tional activities initiated after 30 or more years would beessentially the same as those described for entombment, exceptthat there would be more systems remove

28、d after safe storagethan after entombment.4. Significance and Use4.1 The standardization of decommissioning plans willprovide the nuclear facility owner with a greater assurance thatall basic planning elements and requirements have beenidentified, examined, and addressed.4.2 In applying the guidance

29、 contained in this standard, thenuclear facility owner will address the significant subject areasnecessary to describe a comprehensive decommissioning plan.Additional guidance on the planning of decommissioningprojects, and the preparation of decommissioning plans can befound in such references as N

30、UREG-1727 on decommission-ing standard review plans, and Regulatory Guide 1.179 on theformat and content of license termination plans. Recent newguidance on all aspects of decommissioning is contained in anASME publication titled The Decommissioning Handbook.64.3 This decommissioning plan will be de

31、veloped to serveas the executive document that describes the objectives of thedecommissioning program and identifies and defines the ele-ments necessary to accomplish the program.4.4 A detailed implementation plan describing how theobjectives of the decommissioning plan will be met should beprepared

32、. Some of the documents or implementation plans thatmay be required to support the overall decommissioningprogram include an engineering plan; a cost, schedule, andfinancing plan; a field implementation plan; a health and safetyplan; a quality assurance plan (for example, Guide E 1167); anemergency

33、plan; an environmental report; a radiological pro-tection plan; and a physical security plan. These implementa-tion plans shall be separate from and consistent with thedecommissioning plan.5. Elements of the Decommissioning Plan5.1 The plan should identify and describe the major ele-ments of the dec

36、 facilities:5.2.1 Facility description,5.2.2 Operating history, and5.2.3 A description of the history of operation at the nuclearfacility should be included to provide general information andan indication of the scope of effort required for decommission-ing. This description should include the initi

37、al construction andlicensing history, the operating record, and a summary of alloperating events that could affect decommissioning activities(such as spills or releases of radioactive or contaminatedmaterials).6. Characterization6.1 A description of the entire nuclear facility to be decom-missioned

38、should be provided including results of a radiationsurvey prior to initiation of other decommissioning activities.Site characteristics that should be addressed include topogra-phy, soils and geology, hydrology, seismology, demography,and meteorology. Specific details such as those found in safetyana

39、lysis reports may be provided in appendices or by refer-ence. Plant characteristics that should be addressed include ageneral plant description, a plant structures description, and aplant systems description. Radiological and hazardous materialcharacteristics of the nuclear facility shall be include

40、d as well.The radionuclide inventory for the facility should be presentedwith all of the major contributors identified and quantified.Environmental radiological characteristics of the site should bediscussed.7. Program Objectives7.1 The objective(s) of the decommissioning programshould be stated con

41、cisely. The selected or proposed decom-missioning alternative (dismantlement, safe storage followedby dismantlement, or entombment to unrestricted use levels)shall be included as a minimum.7.2 A qualitative description of any interim status of thefacility should be provided when applicable, that is,

42、 when thesafe storage or entombment alternatives are selected, and whena surveillance/maintenance period is proposed for the facility.7.3 Cleanup criteria should be stated herein, such as NRCRegulatory Guide 1.86, or other specific federal and staterequirements. Termination survey requirements shoul

43、d be asdetailed in 13.5.7.4 The interim and ultimate desired status of all facilitylicenses should be discussed. For facilities where the unre-stricted release criteria will be achieved without a planned andsignificant delay period, this should be stated. For this case, anongoing surveillance/mainte

44、nance program will not be neces-sary.8. Program Management and Administration8.1 The decommissioning plan should include a descriptionof the organization and responsibilities with respect to theoverall program. The discussion should address the decommis-sioning project team, decommissioning manpower

45、; workerhealth and safety training (for example, Specification E 1034and Guide E 1168); and the use, control, and management ofsubcontractors. When safe storage or entombment alternativesare selected, then the organization and responsibilities structurefor the protected storage and delayed dismantle
